So I working on a program that is supposed to accept all letters and make the vowels uppercase. the problem I am having is the isvowel part. I am not sure how to make it work correctly. I think I have the basic structure down, and am probably missing something minor to get it to work. I am a newbie so any help would be greatly appreciated. Oh and I am not sure how to make the or symbol with my computer so that would probably be a good start to helping me.
here's what I have
Code:#include <ctype.h> int main(void) { int c, isvowel(); while ((c=getchar()) !=EOF) if (is vowel(c)) putchar(toupper(c)); else putchar(c); return 0; int isvowel(c) {...}
